Sinus Lift Augmentation
Conditions
Brief summary
thirty implants will be inserted in patients seeking implantation of their lost posterior maxillary teeth (premolar and molars) with limited bone height below the floor of the maxillary sinus, secondary to sinus pneumatization. The patients will be selected from those attending the outpatient clinic of the Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University. 1. Clinical Evaluation • Implant stability 2. Radiographic Evaluation Vertical bone gain (VBG)
Interventions
PROCEDURElateral sinus lift with using allograft and collagen membrane

Primary
| Measure | Time frame | Description |
|---|---|---|
| implant stability | 9 months | the stability of the implants will be evaluated by RFA with the Osstell Mentor device. |
| Vertical bone height | 6 months | vertical bone height will be measured as the distance from the alveolar crest to the new sinus floor at the middle of the implant |
